A Journey Beyond the Wall
Shields Shall Be Splintered: Sacrifice your shield to negate all incoming damage from one attack. Shields crafted from the wood of the rowan tree can be sacrificed for a successful save versus any spell. Magic shields can absorb multiple blows, but will be destroyed once their limit is reached (cumulative 5% chance of destruction after each sacrifice).
Shield Wall: Fighters that form a shield wall anchored on a leader gain +2 to their armor class for as long as they maintain it. Advancing into melee or making a fighting withdrawal may require a morale check. The wall is broken if the leader is incapacitated, if any member fails morale or sacrifices a shield.
